FIG. 4 is a diagram illustrating an antenna structure included in an electronic device, according to an embodiment of the disclosure.

Referring to FIG. 4, an electronic device 400 may include a side bezel structure (e.g., the side bezel structure (218 or 310)) including a plurality of segments. For example, the side bezel structure of the electronic device 400 may be divided through two or more segments. For example, the side bezel structure may include a first conductive portion 411 divided by a first segment 421 a and a second segment 421 b, a second conductive portion 412 divided by the second segment 421 b and a third segment 421 c, a third conductive portion 413 divided by the third segment 421 c and a fourth segment 422 a, a fourth conductive portion 414 divided by the fourth segment 422 a and a fifth segment 422 b, or a fifth conductive portion 415 divided by the fifth segment 422 b and the first segment 421 a

According to an embodiment, at least one of the conductive portions 411, 412, 413, 414, and 415 may be electrically connected to a metal structure 420 included in a support member (e.g., the first support member 311 or a bracket). At least part of the metal structure 420 may be connected to a ground area of a printed circuit board 440 (e.g., the printed circuit board 340).

According to an embodiment, the conductive portions 411, 412, 413, 414, and 415 may be connected to feed parts 411 fa, 411 th, 412 f, 413 f, 414 f, 415 fa, and 415 fb.

For example, the first antenna 411 a may use a first center frequency (e.g., about 2.5 gigahertz (GHz)). The second antenna 411 b may use a second center frequency (e.g., about 2.4 GHz). When the first antenna 411 a and the second antenna 411 b, which use adjacent frequency bands (or commonly using one conductive portion and having a similar antenna length), commonly use one ground part, the radiation efficiency of the first antenna 411 a and the second antenna 411 b may be deteriorated due to mutual interference (e.g., a current applied from the first feed part 411 fa leaks to the second feed part 411 th).

The first antenna 411 a and the second antenna 411 b according to an embodiment of the disclosure may be respectively grounded through paths that are physically separated from each other.

The second ground part 411 gb may be connected to the metal structure 420 through a second ground path (e.g., a conductive member, which is integrated with the first conductive portion 411 or the metal structure 420 and has a thickness and width, each of which is not less than a specific size). In an embodiment, the ground area of the printed circuit board 440 may be electrically connected to the metal structure 420.

The second antenna 411 b including the second feed part 411 th and the second ground part 411 gb may be used as a wireless fidelity (Wi-Fi) antenna (e.g., 2.4 GHz or 5 GHz).

A fourth antenna (not shown) including the fourth feed part 413 f may be used as a mid-band or high-band antenna. A fifth antenna (not shown) including the fifth feed part 414 f may be used as a low-band or mid-band antenna.

When the first ground part in the first conductive portion 411 is used as a common ground of the first antenna and the second antenna (or when the second ground part connected to the metal structure 420 is not present), a leakage current may occur between the first antenna and the second antenna, and thus the antenna performance may be reduced.

For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a compiler or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein, the term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.

The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.

According to various embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. According to various embodiments, one or more of the above-described components may be omitted, or one or more other components may be added.
